Highlights	When both warmth and low weight are crucial, the Ultrasphere 5 is the ultimate packable, featherlight air mat, honed for fast-paced exploring in demanding mountain conditions. Its groundbreaking design includes two layers of TILT, which boosts the mat’s warmth-to-weight ratio by reflecting heat back towards your body, all for a fraction of a gram. It also features new offset air chambers that trap heat within the construction, allowing you to recharge comfortably without the need for high-volume insulation. Highly comfortable and supportive, the Ultrasphere 5 is the ideal foundation for thru-hiking, bikepacking, and multi-day mountain runs. Impressively light at just 345g (size regular), with uncompromised warmth at an R-value of 5.5. The new weight-saving construction uses offset air chambers to trap heat and keep you warm. Two layers of heat-reflective TILT reduce radiant heat loss without adding weight. Comfortable tapered mummy shape that eliminates unnecessary bulk. Soft, exceptionally lightweight 20D fabric. When it’s time to pitch for the night, the two-way valve and inflation sack make camp setup quick and easy. Roll-away stuff sack with repair kit included.

RAB Ultrasphere 5

I received the mat shortly after ordering. It performed reasonably well in conditions of minus 6 degrees. (I was pushing the boundaries here). What I am not happy about is that the mat is sold as weighing 440 grams hence the 4 star rating. The packaging states that the mat weighs 440 grams but when I place it on the scales it weighs almost 100 grams more. This difference being the stuff sack and the inflation sack. This I feel is dubious labeling by RAB and should be clearly disclosed on their packaging. While the mat performed well and is comfortable, I will not be buying future RAB products or recommending them to my friends and colleaugues in the outdoor industry.
